Additional Notes

The DE3175 is the dome light bulb for the Hyundai Tiburon across the 1997-2001 and 2003-2004 model years, while the 6411 applies to the 2005-2006 model years.
Both the DE3175 and 6411 are festoon-type bulbs, meaning they are cylindrical in form and mount between two contact points rather than inserting into a socket.
The 6411 bulb measures 36mm in length and uses an SV8.5 base, which features a metal cap on each end that seats into spring-loaded clips within the fixture.
The DE3175 measures 31mm in length and uses end-cap contacts, making it physically shorter than the 6411 and incompatible as a direct substitute without confirming fixture clearance.
The 6411 carries an explicit 5W rating, operating at 12V, which is standard for automotive interior lighting circuits.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and physical tolerances across those markets.
The difference in base design between the two bulbs, SV8.5 on the 6411 versus end-cap contacts on the DE3175, means the two types are not interchangeable despite both being festoon bulbs.
